_________________________________________________________________________________________________________________________________________________________________
* This specification is subject to be changed without notice.
13. R10~R3F (General Purpose Register)
1. A (Accumulator)
2. CONT (Control Register)
* Bit 5 (TS) TCC signal source
* Bit 6 : (INT)
* Bit 1 (INT0) external INT0 pin interrupt flag .
* Bit 2 (INT1) external INT1 pin interrupt flag .
* Bit 3 (INT2) external INT2 pin interrupt flag .
* Bit 4 (C8_1) internal 8 bit counter interrupt flag .
* Bit 5 (C8_2) internal 8 bit counter interrupt flag .
* Bit 6 ( FSKDATA ) FSK data interrupt flag
* Bit 7 (INT3) external INT3 pin interrupt flag.
* High to low edge trigger , Refer to the Interrupt subsection.
* IOCF is the interrupt mask register. User can read and clear.
* R10~R3F (Banks 0~3) all are general purpose registers.
* Internal data transfer, or instruction operand holding
* It's not an addressable register.
* Bit 0 (PSR0) ~ Bit 2 (PSR2) TCC/WDT prescaler bits.
* Bit 3 (PAB) Prescaler assignment bit.
* Bit 4 unused
* Bit 7 : unused
